Ukwazi izinto eziyisisekelo zesondo lokugaya kuzokusiza ukuthi uthole elilungile

Isondo lokugayakuwuhlobo lomsebenzi wokusika, wuhlobo lwamathuluzi okusika abrasive. Esondweni lokugaya, i-abrasive inomsebenzi ofanayo nowe-serration ku-saha blade. Kodwa ngokungafani nommese wesaha, onezinsimbi kuphela emaphethelweni, isondo lokugaya lisatshalaliswa kulo lonke isondo. Izinkulungwane zezinhlayiya eziqinile ezihuquzelayo zinyakaziswa endaweni yokusebenza ukuze kukhishwe izingcezu ezincane zezinto.

Ngokuvamile abahlinzeki be-abrasive bazohlinzeka ngemikhiqizo ehlukahlukene yezinhlelo zokusebenza ezihlukahlukene zokugaya ekucubunguleni insimbi. Ukukhetha umkhiqizo ongalungile kungadla isikhathi esiningi nemali. Leli phepha linikeza izimiso eziyisisekelo zokukhetha isondo lokugaya elingcono kakhulu.

I-Abrasive: uhlobo lwesihlabathi

Isondo lokugaya noma elinye itshe lokugaya elihlanganisiwe linezingxenye ezimbili eziyinhloko:

Ama-grits empeleni enza ukusika, kanye nenhlanganisela ebamba ama-grits ndawonye futhi isekela ama-grits ngenkathi isika. Ukwakheka kwesondo lokugaya kunqunywa isilinganiso se-abrasive, binder kanye ne-void phakathi kwabo.

Ama-abrasives athile asetshenziswa esondweni lokugaya akhethwa ngokuya ngendlela asebenzisana ngayo nezinto zokusebenza. I-abrasive ekahle yileyo enekhono lokuhlala ibukhali futhi engashwabene kalula. Uma i-passivation iqala, i-abrasive izophuka ukuze yakhe amaphuzu amasha. Uhlobo ngalunye lwe-abrasive luhlukile, lunobulukhuni obuhlukene, amandla, ukuqina kokuphuka kanye nokumelana nomthelela.

I-Alumina iyona evame ukusetshenziswa kakhulu e-abrasive kumasondo okugaya.

Ivamise ukusetshenziselwa ukugaya i-carbon steel, i-alloy steel, insimbi enesivinini esikhulu, insimbi egayiwe ethambile, insimbi ekhandiwe, ithusi nezinsimbi ezifanayo. Kunezinhlobo eziningi ezahlukene zama-abrasives e-alumina, ngayinye ekhiqizwa ngokukhethekile futhi yaxutshwa uhlobo oluthile lomsebenzi wokugaya. Uhlobo ngalunye lwe-alumina lunegama lalo: ngokuvamile inhlanganisela yezinhlamvu nezinombolo. Lawa magama azohluka kumkhiqizi nomkhiqizi.

I-Zirconia aluminakungolunye uchungechunge lwama-abrasives, olwenziwa ngokuxuba i-alumina ne-zirconia ngezilinganiso ezahlukene. Le nhlanganisela ikhiqiza i-abrasive eqinile, ehlala isikhathi eside eyenza kahle ekugayeni okungalungile, njengakumsebenzi wokusika. Futhi kusebenza kuzo zonke izinhlobo zensimbi ne-alloy steel.

Njenge-alumina, izinhlobo eziningana ze-zirconia alumina ziyatholakala.

I-Silicon carbide ingenye i-abrasive esetshenziselwa ukugaya insimbi empunga, insimbi ebandayo, ithusi, ithusi elithambile ne-aluminium, kanye netshe, irabha nezinye izinsimbi ezingenayo insimbi.

I-alumina ye-Ceramicukuthuthukiswa kokhiye kwakamuva kunqubo yokugwaza. Kuyizinhlamvu zokuhlanzeka okuphezulu ezikhiqizwa inqubo ye-gel sintering. Lokhu okulimazayo kungaphula isikali se-micron ngesivinini esilawulwayo. Ngokulandelayo, kwakheka izinkulungwane zamaphuzu amasha. Ama-abrasives e-ceramic alumina aqinile kakhulu futhi asetshenziswa ekugayeni okunembayo okudingayo kwensimbi. Avamise ukuxutshwa namanye ama-abrasive ngezilinganiso ezihlukene ukuze kuthuthukiswe ukusebenza kwawo ezintweni ezihlukene nasezisetshenziswayo.
